摘要

To address environmental issues pertaining to the manufacture, use, and disposal of traditional composites and construction materials, a new class of biobased composite materials is being developed that satisfies acceptable stiffness, strength, and durability criteria while maintaining a desirable propensity for rapid biodegradation. In this study the mechanical properties (in uniaxial tension) and moisture absorption behavior of biobased composites derived from poly(??- hydroxybutyrate)-co-poly(??-hydroxyvalerate) (PHBV), a naturally occurring biopolymer reinforced with a lignocellulosic functional filler of oak wood flour (OWF), has been investigated and characterized experimentally. The results obtained herein serve as a baseline comparison in ongoing work related to the mechanisms and impact on mechanical behavior, material durability, and biodegradation property effects of fiber-matrix compatibilization techniques.
